Widora-air board is a development board featuring the brand new ESP32, a dual-core 32-bit ARM MCU, offering super computing and communication performances with open source environment for fast and easy applications development under various platforms and ecosystems.The ESP32 MCU is a Dual Core 32-bit ARM MCU cadenced up to 240MHz, each core can be powered and controlled separately,. The ESP32 offers 650DMIPS of computing power and features 512K of SRAM, HT40 Wifi, BT4.0 and standard Bluetooth, multiple peripherals and more GPIO than ever.

This Widora-air development board is the perfect platform to use this ESP32. It offers csamll footprint and headers for convenient use in breadboard, or directly, a micro USB socket , automatic download / debug / Log abilities thanks to the new high USB-UART bridge from Silicon Labs CP2104. An automatic reset circuit makes programming with Arduino and others IDE a breeze. PCB layout a been well optimized in its current 4.0 version, all IOs are broken out. The board has it own onboard 3.3V LDO, two keys and two LEDs. Reduced footprint of 61.6 x 17.7 mm (2428x700mil).
